Description

200848473 IX. Description of the Invention: [Technical Field] The present invention relates to a pigment dispersion composition, a photocurable composition, and a color filter, and a process for producing the same. [Prior Art] In general, a practically usable pigment which exhibits a vivid color tone and a high coloring power is composed of fine particles. However, when the pigment particles are more refined for high coloring power, the pigment dispersion composition tends to exhibit high viscosity, which is not only taken out from the disperser of the pigment dispersion composition, but also becomes difficult to transport via the pipeline, and gelation occurs during storage. It is difficult to use. One of the fields of use of the pigment dispersion composition is a color filter used for a liquid crystal display or the like. The color filter is a coloring photosensitive composition by using a polyfunctional monomer, a photopolymerization initiator, an alkali-soluble resin, and other components in a pigment dispersion composition in which an organic pigment or an inorganic pigment is dispersed to form a coloring photosensitive composition. It is manufactured by the lithography method. In recent years, color filters have been used in liquid crystal display (LCD) applications, not only for monitors but also for televisions (Television: TV), and tend to expand with this use. The color characteristics of the chromaticity, contrast, etc. are required. Further, in the use of a solid-state image sensor (Image sensor), high color characteristics are also required. In response to the above-mentioned requirements, it is sought to disperse the pigment in a fine state (good dispersibility) and to disperse it in a stable state (good dispersion stability). When the dispersibility is insufficient, streaks (edges on the edge) or surface irregularities may be formed on the colored resist film, and the color filter or the ruler of 200848473 inch of the manufactured color filter may be reduced, or the contrast may be significantly changed. Poor question. When the property is insufficient, in the manufacturing step of the color calender sheet, the following problems are caused: the coating step of the coloring photosensitive composition is lowered; in the exposure step, the photosensitivity is lowered; the alkali solubility is lowered. In addition, when the dispersion of the pigment is stabilized over time, the composition of the photosensitive composition is colored to increase the viscosity, and the application period (P 01 1 ife) becomes extremely short. However, the particle size of the pigment is made fine. In the case where the surface area is increased, the cohesive force between the pigment particles is increased, and it is often difficult to coexist the dispersibility and the dispersion stability. In order to solve such problems, various types of inspections have been carried out. For example, as a pigment dispersant, there are two proposals for using an alkali agent and an acidic pigment dispersant (for example, JP-A-2002) on JP-A 02 0 2 - 2 9 In the case of No. 6 7 7 0, it is presumed that the alkaline pigment enhances the dispersibility in the pigment dispersion, and the acidic has a holding action when the alkali-soluble binder is added after the dispersion. On the other hand, it is disclosed at the end of the polymer. It has a dispersing agent (for example, JP-A-9-7791). By introducing an organic color only at one end of the polymer portion, the dispersing agent is adsorbed on the surface of the pigment with high efficiency while the dispersion medium has Adequate affinity ensures the dispersion of the anchor layer. In addition, it is also revealed that the dispersion is particularly prone to occur only at the end of the polymer portion. The uniformity of the film thickness is in the imaging step, and when the property is poor, the composition also occurs. Condensation straight. Distribute the level of pigment particles. Sexual pigment dispersion • No. 296770). The dispersant is a pigment 9-77994 medium or heterocyclic ring having a pigment dispersant-dispersion-functionality functional group, and the polymerizable portion and the sufficiently fixed end-end are introduced into a polymerization of a sulfonic acid 200848473-based or monosulfate group. A pigment dispersant (for example, JP-A-2002-273 191), which adsorbs a sulfonic acid with high efficiency by a pigment surface (especially a basic pigment) while having a sufficient affinity for a polymer portion and a dispersion medium. It ensures a stable and stable adsorption layer. However, in the pigment dispersant described in JP-A-2002-296770, cross-linking can be formed between plural pigments by using an alkaline pigment dispersant and an acidic pigment dispersant. Further, the acidic pigment dispersant is not used to improve the dispersibility of the pigment, and although the dispersant is used, the dispersibility and stability of the pigment are not necessarily sufficient. Further, the pigment dispersant described in JP-A No. 9-77994 does not introduce a plurality of organic dyes or heterocyclic rings at the end of the polymer, and since it is difficult to introduce, it is difficult to say that the adsorption to the surface of the pigment is sufficiently strong. Therefore, it is impossible to ensure that the adsorption layer is sufficiently dispersed and stabilized. Further, in Japanese Patent Laid-Open Publication No. Hei 9-7 7994, it is not described that the dispersibility and dispersion stability can be improved by using other dispersants. In addition, the pigment dispersant described in JP-A-2002-273 119 introduces a terminal group based on a polymer reaction, and it is difficult to say that it is a synthetic method for industrially advantageous production of a pigment dispersant. In JP-A-2002-273 119, there is no description that the dispersibility and dispersion stability can be improved by using other dispersants.

For example, a germanium substrate or the like, or a complementary metal oxide semiconductor (CMOS). These substrates may also be formed with a black matrix for isolating the pixels. Further, on these substrates, an undercoat layer (other layer) may be provided as needed for improving adhesion to the upper layer, preventing diffusion of substances, or planarizing the surface of the substrate. As a method of applying the photocurable composition of the present invention to a substrate, various coating methods such as slit coating, inkjet method, spin coating, cast coating, roll coating, and screen printing can be employed. The coating film thickness of the photocurable composition is preferably in the range of 0.1 to 10 μm, more preferably in the range of 0.2 to 5 μm, and particularly preferably in the range of 2 to 3 μm. Inside. The drying (prebaking) of the photosensitive film coated on the substrate can be carried out at a temperature of 50 ° C to 140 ° C for 1 〇 to 300 ° using a heating plate, an oven or the like. (Exposure step) In the exposure step, the photosensitive film formed in the photosensitive film forming step is subjected to exposure by exposure to a mask having a predetermined mask pattern, i.e., -103 to 200848473. In this step, by exposing the photosensitive film to the coating film by specifying the mask pattern, only the portion of the coating film irradiated with light can be made. As the radiation which can be used at the time of exposure, it is particularly preferable to use ultraviolet rays such as g-line or i. The irradiation amount is preferably in the range of 5 to 1 500 mJ/cm 2 , more preferably in the range of 10 to 1000 mJ/cm 2 , and most preferably in the range of ι 500 mJ/cm 2 .

The best range is 80~5 00mJ/cm2. (Dynamic Step) Next, by performing development processing, the unexposed portion in the exposure step is eluted into the developing liquid, and only the portion which is photocured remains. As the development, as long as the film of the photocurable composition of the uncured portion is dissolved on the one hand, the hardened portion is not dissolved, and either of them may be used. Specifically, a combination of various organic solvents or an aqueous alkaline solution can be used.

Further, when a developing solution made of such an alkaline aqueous solution is used, it is usually washed with pure water after development. After the development step, the excess imaging liquid is removed by washing, and after drying, heat treatment (postbake) is performed. The post-baking is usually carried out by heat hardening at 100 ° C to 2 40 ° C in order to heat-treat the image after complete hardening. When the substrate is a glass substrate or a ruthenium substrate, the heat hardening treatment temperature is preferably in the range of 200 ° C to 240 ° C in the above temperature range. This post-baking treatment can heat the coating film after development under the above conditions, using a hot plate or a convection oven (convection oven), a high frequency heater, and the like. The means are carried out in a continuous or batch manner. The color filter formed of the desired hue is produced by repeating the photosensitive film forming step, the exposing step, and the developing step (and optionally heat treatment) as described above to repeat only the desired number of hue. When the photocurable composition of the present invention is applied to a substrate to form a film, the dry thickness of the film is generally in the range of 0.3 to 5.0 μηι, preferably in the range of -105 to 200848473 〇·5 to 3·5 μπι. , preferably in the range of 1.0~2·5μηι. Examples of the substrate include an alkali-free glass, a soda glass, a PYREX (registered trademark) glass, a quartz glass, and a transparent conductive film or the like, which is used for a liquid crystal display element, or a solid-state image sensor. A conversion element substrate such as a germanium substrate or the like, and a plastic substrate. On these substrates, a black matrix for isolating the pixels is usually formed. Preferably, the surface of the plastic substrate has a gas barrier layer and/or a solvent-resistant layer as the photocurable composition of the present invention, although the use of the color filter is mainly used as a main body. However, it is of course also applicable to the black matrix provided between the pixels of the color filter. In the black matrix, in addition to the black coloring agent such as carbon black or titanium black which is used as a coloring agent in the photocurable composition of the present invention, pattern exposure can be performed in the same manner as in the above-described method of producing a pixel. Alkali development is then carried out by post-baking to promote hardening of the film.
